Punch a Slew of Holes, Distortion-Free
July 22, 2013Comments

Now, with integrated flattening, opposing stresses are introduced to keep the sheetmetal panels flat, eliminating post-process flattening. The function is available on Trumpf’s TruPunch 5000 punching machine and TruMatic 7000 punch-laser combination machine. It works thanks to a convex die working in tandem with a concave stripper that features a recess and special coating. The convex die presses the sheetmetal against the stripper from underneath, to overbend the material. The concave stripper counteracts by pressing the material raised by the die back downward at the edge of the die. The overbending creates counter-stresses, which offset the compressive and tensile stresses caused by the punching process.
The end result: the material leaves the machine flat.
